The only way for 3rd wave to work is if multiple distros agree to adopt it. Since these tools don't even agree on an interface, IMHO it wouldn't be much different than what we have. I also don't like the fact that some tools native skip things like what's in ".gitignore". I don't want a tool that does that by default. If there was a consortium to standardize a new *nix CLI, then maybe it could get some traction.
